Belt known that I, J 0511* W. MONA'EAN, a cit zen oft-he United States; vre'sidingnt Providence, in the county of Providence-and new and useful Improvements mil/{0130R- Trucks Having Dumping-Bodies the following 1S ahpecificationf nvention relates to improvem ents inself-propelled or motor-trucks having dump ing bodies, end it consists in the novel con struction, combination and arrangement of parts, all as more fully hereinafter set forth and'claime-d'. y 7 I am, of course, well aware that ho'rse-- drawn vehicles or trucks havin' dumping bodies have been devised and produced prior 3 to my improved motoratrucky'the latter, v however, differs froin's'aid former construe.- 20. vtions in that in adapting the bodies o,f.mo'-. tor-trucks to be tilted or swung up and down from the ivot point, the matters of power' ease and relative rapidity andfacility'o operation are to." be considered. 5 Moreover, ,5 the bodies of'motor-trucksare as a ru le capable of much greater capacity or load than.

animal-drawn -\vag0n bodies" In other 'words, an operator of my improved motor: truck body is enabled to handle or swing the latter, including its load, withlelssefi, fort or exercise of manual power than is. usually expended in manipulating the ti1t-' able body of a horse-drawn vehielehaving fless carrying capacity. Y,

In the accompanying sheet of drawings; illustrating my improvement, Figure 1 rep-' resents, in side elevation, the dumping body and the mechanism foroperuting .itmounted on the frame and chassis of a motor-truck, the swinging body being in the lowered or normal position; 'Fig.- 2 is a similar view showing the movable body part in the maxisectional view taken on ]'ine'3'3 of Fig. 1,- 4L5 Fig. 4 is ahorizont'al eross-sectional/view, enlarged, of the main driving-pinion and its frame, taken on line 4-4 of ig. 1; Fig. 5 is a side view'of a ratchet device adapted to be A employed in connection with the elevating or operating mechanism; and Fig. 6 1s anend view of it. ,i I
